What is Fallom?

Fallom is an AI-native observability platform for LLM and agent workloads that lets you see every LLM call in production with end-to-end tracing, including prompts, outputs, tool calls, tokens, latency, and per-call cost. We provide session/user/customer-level context, timing waterfalls for multi-step agents, and enterprise-ready audit trails with logging, model versioning, and consent tracking to support compliance needs. With a single OpenTelemetry-native SDK, teams can instrument apps in minutes and monitor usage live, debug issues faster, and attribute spend across models, users, and teams.

Fallom's Core Features

OpenTelemetry-native SDK

One OpenTelemetry-native SDK to instrument LLM and agent calls in minutes, enabling seamless integration with existing telemetry pipelines and minimal engineering effort.

End-to-end Tracing & Waterfalls

Full per-call tracing including prompts, outputs, tool calls, tokens, latency, and multi-step timing waterfalls for agents to visualize each step of complex flows.

Cost & Usage Attribution

Per-call cost tracking and aggregated spend reports that attribute usage and model costs to users, sessions, and teams to control spend and inform model selection.

Session & Contextual Insights

Session- and user-level context capture (customer data, conversation state) to understand behavior across requests and reproduce issues with full context.

Enterprise Audit Trails & Compliance

Logging, model versioning, consent tracking and immutable audit trails to support security, compliance, and governance requirements.
